Display screen with an animated graphical user interface



FIG. 1 is a front view of a first image of a display screen with an animated graphical user interface, showing our new design;

FIG. 2 is a front view of a second image; and,

FIG. 3 is a front view of a third image.

The appearance of the animated graphical user interface sequentially transitions between the images shown in FIGS. 1-3.

The process or time period in which one image transitions to another image forms no part of the claimed design.

The dot-dash broken line showing a display screen illustrates the environment of the design and forms no part of the claim. The evenly-dashed broken lines illustrate characters, symbols and other features of the graphical user interface that form no part of the claimed design. 

CLAIM The ornamental design for a display screen with an animated graphical user interface, as shown and described.
